Technical Specifications

The SFH2701 typically has a collector-emitter voltage (VCEO) of 30V, a collector current (IC) of 50mA, and a power dissipation of 100mW. Its spectral sensitivity is optimized for wavelengths around 880 nm to 950 nm, commonly used in infrared LEDs. The angle of half intensity is typically ±20 degrees, providing a focused detection area. The response time is typically a few microseconds, enabling fast switching speeds. The operating temperature range is usually between -40°C and +85°C, allowing for use in a variety of environmental conditions. The package is a standard T-1 3/4 (5mm) through-hole package, making it easy to solder and mount on printed circuit boards. The device is also sensitive to ambient visible light, so proper shielding might be necessary in some applications.
